The sensing module 60, the key module 70, the touch module 80 or the voice module 90 can respond to the requirement of the target user and convert the requirement of the target user into an electric signal, and the control module 50 generates a driving signal according to the electric signal representing the requirement of the target user to control the color-changing display lens 20 to be colored at the target light transmittance. This arrangement may further satisfy the adjustment requirements of the smart glasses 10 by the target user.
Optionally, fig. 8 is a schematic structural diagram of another smart glasses provided in the embodiment of the present invention. On the basis of the above embodiment, referring to fig. 8, the smart glasses may include the collection module 100, the collection module 100 may be a camera or a photosensitive device, and taking the photosensitive device as an example, the photosensitive device detects light intensity data of an environment where the smart glasses are located, the photosensitive device receives the light intensity data and converts the light intensity data into an electrical signal, and the control module 50 receives the electrical signal and generates a driving signal according to the electrical signal. The intelligent glasses adjusting device can meet the adjusting requirement of a target user on the intelligent glasses, and can also perform active adjustment according to the ambient light intensity data under the condition that the target user is not adjusted, for example, the target user is not used to self-adjusting, inconvenient to adjust or cannot get to adjust, so that the visual experience of the target user is further improved.
Optionally, on the basis of the above embodiments, with reference to fig. 6 and fig. 8, the smart glasses 10 further includes a light engine 120 (also called optical engine, i.e. image source), the light engine 120 may be disposed on the frame 30, the light engine 120 corresponds to the second through hole 6 of the color-changing display lens 20, and the light engine 120 is configured to form and project light passing through the color-changing display lens 20.
Specifically, the Light engine 120 may include various types of Micro-display devices including, but not limited to, Micro-LEDs, Micro-OLEDs, laser-integrated Micro-mirror scanning LBS, LCOS (liquid crystal on silicon microdisplays), DLP (Digital Light Processing), silicon-based OLEDs, and the like. The second through hole 6 is disposed at the edge of the color-changing display lens 20, and can be at least partially coupled into the light engine 120 and directly face the light engine, so as to improve the light transmittance of the color-changing display lens 20 and avoid the influence of the low light transmittance of the protective layer 5 on the display effect of the light engine 120 on projecting light to the display layer 1. The protective effect of the protective layer 5 on the display layer 1 is improved on the one hand, the display effect of the display layer 1 can be guaranteed on the other hand, and the visual experience of a target user is further improved.
The second through hole 6 is at least partially opposite to the light engine 120, and for example, the projection of the second through hole and the coupling-in structure of the optical waveguide in the direction of the coupled-in image light partially overlaps or completely overlaps, and for example, the projection of the coupling-in structure of the optical waveguide in the direction of the coupled-in image light falls into the projection area of the second through hole.
It should be understood that various forms of the flows shown above may be used, with steps reordered, added, or deleted. For example, the steps described in the present invention may be executed in parallel, sequentially, or in different orders, and are not limited herein as long as the desired results of the technical solution of the present invention can be achieved.
The above-described embodiments should not be construed as limiting the scope of the invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may be made in accordance with design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
